cube 1 3 x 3 x 3
cube 2 4 x 4 x 4
One 3x3 face will be gone (covered) as will a 3x3 area on one of the faces of the larger cube
3x3 x 5 + 4x4 x 6 - 3x3 = 45 +87=132 cm2
Original painted surface area = 2 ( 3 x 6 + 6x8 + 8x3) 180 cm^2
After making it 1 cm^3 there are 3 x 6 x 8 cubes each with 6 cm^2 surface area = 864 cm^2
864-180 = 684 cm^2 unpainted
9.95p + 8.01p <= 50 , so p <= 2 This answer is not listed....did you make a typing mistake for 'A' ?
OUTPUT = 3n + 1
TWO digit numbers that are 1 greater than a multiple of 8 would be 17 25 ..... as guest posted
Adding 6 to x shifts things to the LEFT:
y = 3 (x+6)^2 + 5(x+6) + 2
y = 3x^2 +36x+ 108 + 5x + 30 + 2
y = 3x^2 + 41x + 140
You are given the 'zeroes' (x axis intercepts), ( -3 and 8) so the equation is this :
y = ( x+3)(x-8) <===== expand to the form requested
2.5 ton * 2000 lb/ton / (20 lb/lot) = 2.5 * 2000 /20 lots = _______________lots
The vertical axis of symmetry is x = -12 the x intercepts are on either side of this at the same distance
the second intercept will be at x = 6 ( 6,0 )
I SHOULD be out 'there' putting my car back together that is scattered all over the driveway.....but it is still kind of cold....maybe later...haha...
